Abstract-IP/MPLS and Optical technologies are the foundations of current Carrier-Grade Networks (CGNs), due to both the flexibility of IP/MPLS to provide services with distinct requirements and the high transport capacity offered by new Optical technologies, such as Elastic Optical Networks (EONs). However, despite of the widespread adoption of these two technologies, interoperability issues still impact on key network features, in particular on resilience capabilities. Resilience is gaining momentum in recent years due to the advent of new CGN scenarios, such as Data Center Networks (DCNs), where a link or a node failure might lead to a substantial traffic loss. We consider that any potential contribution on the resilience arena, must be built on top of a solid knowledge of available proposals emphasizing most appealing research trends and the limitations affecting the management of resilience in CGNs. Aligned to this scenario, the main goals of this article are: (1) compile distinct approaches for managing resilience; (2) describe in a comprehensive manner, the challenges faced by CGN operators in order to manage resilience; (3) show why current solutions for managing resilience do not completely address the interoperability issues present in multilayer CGNs with multi-vendor settings, and; (4) provide insights for future trends.

“…The Service-oriented MGON (MultiGranular Optical Network) [24] is fine-grained service-oriented network architecture that has been proposed for cloud environment. This solution provides a mapping strategy of application requests expressed in terms of QoS parameters (e.g., delay, bandwidth) to technology-specific attributes (e.g., burst size, wavelength, path) in order to offer different levels of service granularity to clouds.…”

Network virtualization is considered as a promising way to overcome the limitations and fight the gradual ossification of the current Internet infrastructure. The network virtualization concept consists in the dynamic creation of several co-existing logical network instances (or virtual networks) over a shared physical network infrastructure. We have previously proposed a service-oriented hierarchical business model for virtual networking environments. This model promotes the idea of network as a service, by considering the functionalities offered by different types of network resources as services of different levels -services that can be dynamically discovered, used, and composed. In this paper, we propose an open, virtual, multi-services networking architecture enabling the realization of our business model. We also demonstrate the operation of our architecture using a virtualized QoS-enabled VoIP scenario. Moreover, virtual routing and control level performance was evaluated using proof-of-concept prototyping. Several important findings were made in the course of this work; one is that service-oriented concepts can be used to build open, flexible, and collaborative virtual networking environments. Another finding is that some of the existing open source virtual routing solutions such as Vyatta are only suitable for building small to medium size virtual networking infrastructures.

“…27 An operational signaling solution able to support such 28 cross-layer interactions, including network programmabil- 29 ity, is not available in legacy IP-based networks. Noteworthy 30 initiatives, such as IP Multimedia Subsystem (IMS) [6], Next 31 Generation Networks (NGN) [7] and Next Generation Service 32 Overlay Networks (NGSON) [8], aim at the definition of more 33 advanced and effective network architectures, also including 34 service-oriented capabilities. Nonetheless, their actual im- 35 plementations and deployments are either very limited or 36 tailored to specific application scenarios [9].…”
